The image depicts a graph with two axes: one vertical axis on the left side labeled "y" and one horizontal axis at the bottom labeled "x". The graph shows a wave-like pattern that oscillates above and below a central line, which represents zero. This central line is drawn as a straight horizontal line across the middle of the graph.

The wave starts from the origin (0, 0) on the x-axis and y-axis respectively. It rises to its peak at approximately (π/2, 1), then falls back down to cross the x-axis again at π. After this point, it continues to oscillate, reaching a trough below zero around (3π/2, -1). The wave then rises again towards another peak near (5π/2, 1) before falling back and crossing the x-axis once more.

The peaks of the wave are marked with red dots at coordinates such as (π/2, 1), (5π/2, 1), etc., while the troughs are also marked with red dots. The graph is smooth, indicating a continuous function without any sharp corners or breaks in its path.

There are no people depicted in this image; it solely consists of mathematical elements: axes, labels, and points on the wave pattern.
